fixedColumns: remove scroll bars at the bottom of fixed columns

I am new to Datatables and I try to implement a simple table where the first and last columns are fixed, and I can scroll horizontally through the columns in between.

When I activate "scrollX" : true in the datatable creation, I get the expected scrolling bar at the bottom of the table but I also get scrolling bars at the bottom of each fixed column. I've included a screenshot below.

I could not find any fix so far, do you have any idea how to remove the scroll bar in fixed columns ?
